Why are thumbnails harder to care for?

[Evaradero]

I was just going off of imitators since those seem to be some of the more popular of the thumbnails. I have a couple different imitators who have gotten aggressive if their vivarium wasnt planted/designed properly

Yeah some do not get along great in groups for sure, just wanted to make sure we didn't do a blanket statement and accidentally lead someone astray.

I have found that once they've been in their enclosure for awhile they stop trying to escape. It is true though, the second they see a door open they take off.

With Imitators I still have not had luck keeping them in groups. There are people who have success with keeping 2 pairs together in something like a Exo Terra 18x18x24. If I remember correctly that's how Lynn keeps her Varaderos. Mine refuse multiple frogs and I can only keep my Varaderos as pairs. I have a trio of Nominant imitators together in a 12x12x18 and so far everything is fine, but one day the two males might start fighting.

One other thing about thumbnails is that they are Typically more expensive than Leucs or Tincs, depending on what species you get.
